I am a R/c model aircraft builder and have been using Dura Grit carbide abrasive tools since 1993. I have found that they are the best abrasive tools available for the hobby.

I am particularly happy with the SD2 series of replacement sanding bands for the Dremel 1/2" sanding drums. These light weight tools slip onto the stock Dremel rubber mandrels more accurately than the fibre sanding band and because of this feature, there is virtually no vibration at any speed.

I also enjoy the fact that I do not have to keep replacing the sanding band anymore, the durability is outstanding. Also, the safety factor is very good, they don't come apart under heavy usage as is common with the disposable sanding bands, particularly at high speed settings.

I consider the SD2 series is another well designed tool from Dura Grit, thank you, a very loyal customer.
